1907ad9c91 Move 'mutating' and 'nonmutating' onto the new attribute processing machinery.
Also:
 - merge the test/decl/func/functions_new.swift testcase into test/Sema/immutability.swift,
   where the bulk of similar tests are.
 - Move the type checking logic for 'dynamic' out of ValidateAttrs into TypeCheckAttrs
 - Change the encoding for 'override' to 49 so that stuff vbr's so much more densely :-)

fe30b66a93 move "override" onto the new fangle decl modifier code, instead of being a virtual
attribute.  As part of this, introduce a new "NotSerialized" flag in Attr.def.
This eliminates a bunch of special case code in the parser and elsewhere for handling
this modifier.

ea8b7a471a Extend the attributes machinery to enforce the "OnFoo" flags in Attr.def at sema time, and extend
them to cover all declaration types.

This ensures that we reject attributes on declkinds where they don't make sense.  I went so far
as to make the QoI decent when an attribute can only be applied to a single kind of declaration
to make sure the error message says "@IBAction is only valid on 'func' declarations" as well.

This resolves <rdar://problem/17681151> 'dynamic' accepted by the compiler where it shouldn't be

8991456ff2 Switch infix/postfix/prefix to be declaration modifiers instead of attributes,
eliminating the @'s from them when used on func's.  This is progress towards
<rdar://problem/17527000> change operator declarations from "operator prefix" to "prefix operator" & make operator a keyword

This also consolidates rejection of custom operator definitions into one
place and makes it consistent, and adds postfix "?" to the list of rejected
operators.

This also changes the demangler to demangle weak/inout/postfix and related things
without the @.

f4296846b0 [Serialization] Allow witness conformances to be "incomplete" when writing.
This just means we haven't deserialized them properly yet. As soon as we
try to /do/ something with the conformance, we'd pull in what we need, but
for reserializing (i.e. module-merging) we can generally just keep going.

04095fb5aa *Start* importing more availability information from the SDK.
This is a WIP.  This patch includes:

- Adds version tuple information for 'introduced', 'deprecated',
  and 'obsoleted' to the 'availability' attribute.

- Add Clang importer support to import __attribute__((availability))
  version tuples into Swift as pieces of the 'availability'
  attribute.

- Add serialization support for the 'availability' attribute with
  this extra information.  This is not tested other than the
  tests currently passing.  This is not expected to be
  really exercised (with interesting versions) until
  parsing support is added for the version tuples.  However,
  existing @availability attributes in the test suite are being
  serialized, which should just include "empty" version information.

What's not in this patch:

- Parsing support in Swift for 'deprecated', 'introduced', or
  'obsoleted'.  All of this information is currently being pulled
  in from the Clang Importer.

- Warning support for using deprecated declarations based on the
  availability information and the minimum deployment target.

- Some harmony reconciling the 'IsUnavailable' field in
  AvailabilityAttr, which attempts to eagerly compute if something
  is unavailable so we don't have to replicate the checking logic
  elsewhere.  The idea is that when we either import availability
  information or lazily deserialize it we can compute whether or
  not something is conditionally unavailable or deprecated right
  there, and not have to have all clients within the frontend
  of the availability information need to pass the minimum
  deployment target.  Right now 'IsUnavailable' is also used
  to encode if the attribute represents unconditional unavailability,
  e.g. @availability(*, unavailable).

This patch, however, should contain enough information to start
looking at implementing weak linking support.

NOTE: the serialization of the attribute is a bit ugly.  I wasn't
certain if Jordan's serialization meta-programming supported
serializing values that decomposed into multiple values in a record,
so this ugly macro-based implementation is in place which compacts
all the version tuple information for an availability attribute
into a single record.

304361b015 Serialization: add initializer cross-references that also include the kind of initializer (designated, convenience, etc.).

We add one more field to SILFunctionLayout for semantics. We should refactor

d9d451cea5 SIL: Add unchecked_{trivial,ref}_bit_cast instructions.
These instructions do a bitcast operation without stack traffic (at the SIL level). unchecked_trivial_bit_cast represents a conversion from a potentially nontrivial type to a trivial type, such as from a class reference to Int. unchecked_ref_bit_cast represents a conversion between types for which retain_value and release_value has equivalent effects when applied on the input or output values.

cc6e3e8d03 Fix some issues with type checking indirectly recursive protocol requirements
These changes prevent a certain class of bogus errors, as well as several crashers. Unfortunately, though, they don't quite get us to the point where we can broadly use recursively defined protocol requirements, in the standard library.  (To do so would require significant changes across the entire stack.)

b3e72be9d9 Remove unused deserialized SILFunctions.
The deserializer holds a reference to the deserialized SILFunction, which
prevents Dead Function Elimination from erasing them. 

We have a tradeoff on how often we should clean up the unused deserialized
SILFunctions. If we clean up at every optimization iteration, we may
end up deserializing the same SILFunction multiple times. For now, we clean
up only after we are done with the optimization iteration.

5219bb0be2 [serialization] Type and value cross-references are mutually exclusive.
In Swift, a type and a value (such as a function) will never have the same
name, but we import C tag types (structs, unions, and enums) into the same
namespace as values, which can lead to ambiguity. If the user has managed
to make clear which one they want in source code, though, we should preserve
that information during serialization.
